Question

我有3行字符串。它们是正确的，但是当我们尝试创建MultiLineString时，SQL Server 2008会引发异常：

System.ArgumentException：24200：指定的输入没有代表一个有效的地理实例。

我没看到错误在哪里。有人可以帮帮我吗？

Answer 1

错误在G6线的某处。关于你定义的第二和第三个线串的东西都失败了 - 可能两个都有一个共同的重叠段，这是不允许的。

Answer 2

我再次阅读msdn。你是对的。 2.包含MultiLineString实例的两个LineString实例可能在一个时间间隔内重叠

问题的解决方案可能是将此数据存储为多点，但如果我们选择此选项，我们将遇到STDistance问题。如果您保存为多线串或多点，结果会有所不同。

解决方案是使用GEOMETRY COLLECTION！

再次感谢您的帮助
